This invention relates to improvements in I brushesl and is particularlydirected to that `classr of brushes wherein the bunch of bris'-V tlescontains a wedge to expand the same into engagement with a surroundingmetal ferrule or band.

. The present invention especially resides in the means for securing thebunch of bristles to the handle.

The invention is illustrated in the accomn panying drawing, whereinFig. 1. shows the brush in side elevation.`

- spective.

Referring to the drawing the numeral 5, designates th-e bristles of thebrush which are Varranged in a. bunch and are encircled by a metalferrule 6 which latter has the shap the brush is to assume.

.Into the butt-ends of thebunch of bristles, 1

I drive two wedges 7 which latter are spaced K apart in that they arearrangedon oppo :io site sides of aV central'line passing'thro-ugh i.the bunch of bristles.

This arrangement 'provides a central filling. of bristles. 8 'betweenthe outer sides of the wedges andthe ferrule. Y

During theformation of the bunch of bristles I preferably, but notnecessarily, place a central tube'lO in the central filling 8 yofextends preferably from the upper to the lower edges of the wedges, asseen in Fig. 2m

Y of theV drawing. Y

It will be noted byv reference to Fig. 3 `of the drawing that bristlesare provided all around the central tube 10so that the only cavitybetween the wedges is at the center of the'brush and that this centralcavity is only the diameterof the tube. y

The metal ferrule or band 6 is so placed on the bunch of bristles as toproject slightly above the root ends thereof and there-by form acavityor socket on top of the bunch, :Into this cavity or socket thelower end of the handle is to be placed, as will presently be described.

The handle 11, in this instance, is Hat on two vsides and has aliange`portion 12aty its base. This flange portion is of a width* and depth tosnugly tinto the'soclret over the butt-ends of the bristles, and when soplaced, the handle will practically seat on the upper rasata surfaces ofthe two spaced-apart wedges and y over the upper end of the'central tube10. After the handle is in placethe bristles vof the bunch are spreadopen at the center and a fastening 13, carrying a lateral proj ection ora head 14, is passed up through thel tube 10 and entered in the bottomof the handle -until the lateral projection orhead 14 seats against theunder side of the tube and also preferably against the bottom edges ofthe two spaced-apart `wedges, as clearly shown in Fig. 2, and thehandleis thereby lsecured directly to the bunch'of` "bristles t.

By preference, I form the head n or the fastening in such away as toprovide an upwardly-extending projection 17, whose shape will varyaccordingto the shape of the head and the character of the fasteningdevice.`

The upwardly-extending projection 17 of whatever form it may be will beembedded in the two spaced-apart wedges whereby it will serve to holdthe vtwo wedges from ,bulgingv laterally at opposite sides of thecentral tube 10 or the'hole through which the fastening passes in casethe tube is omitted. Y For purposes of finish, I usually place a leatherband 15, around the outer side of the butt-ends thereof, two Vspacedapart parallel 1 disconnectedrwedges inthe butt-ends ofthe bunch, awoodenhandleabove the wedges and a fastening extending up between thetwo parallel wedges and into the handle said fastening having a headlwhich extends across the space between and engages the under sides oftheparallel wedges said head having means to prevent the wedges fromspreading apart.

2.'In a brush the combination with a butt-ends` of the bunch, a handleabove the 'wedges and a fastening extending up between the two wedgesand into the handle said fasteningehaving a head of a size to eX- tendacross th-espace betweenmthe wedges and said head havingupwardly-extending projecting ineansv thereon which latter enter thematerial of the wedges and hold the same from spreading apart.

V.3. In a brush the combination Vwith a bunch vof bristles, of a: bandaround the butt-A ends thereof, two spaced aloartk wedges in ,to extendacross the espaceV` between the wedges and each arin of the head havinga projection thereon to enter the wedge above it whereby the two wedgeswill be held from spreading apart. v

In testimony whereof I aflix my signature.
